ALS21 Absolute Linear Magnetic Sensing Head The Absolute Magnetic Sensing Head ALS21 combined with BOGEN‘s magnetic scales offer cost-efficient magnetic measurement solutions for many industrial applications where movements or positions have to be measured. ALS21 can be used for linear measurements up to 8100 mm length with a resolution up to 1 µm. The measuring head provides both BISS-C or SSI outputs, including incremental signal output in parallel. Thanks to IP67 class protection and rugged mechanical design ALS21 can be implemented even in harsh industrial environments. Absolute Measuring Linear Applications Features and Benefits • BISS & SSI interface • additional incremental output for speed feedback • resolution up to 1 μm ALS21 rev 1.0 (2021/08/26) • error bit ouput • measuring length up to 8,1 m • high mounting tolerances
